1. From the present study of the histological investigation of 34 human embryos the 4 th week-the end of 4 th month of development stage, it seems to be rather doubtful that the reduction of dental lamina and the penetration of vessels into enamel organ are to the largest extent achieved by the mesenchymal cells, as hitherto believed.
2. In the earlier stage of tooth germ formation, ectoderm cells have the latent potency of mesenchyme.
3. The ectoderm cells are able to differentiate into the erythrocytes ; that is, the latter in the dental lamina and the enamel organ has its origin in the former.
